Red shift!

Professor Chaos: holy crap! Yes, I have Solar Quest. Used to play it all the time with my parents/sister when I was a kid, and now I have it under my coffee table, along with Carcassonne, Settlers of Catan, Monopoly, Scrabble, Mastermind, Ticket to Ride, and probably some others that I can't remember now. Of those, I think I like Carcassonne the most but haven't played it since we got the Xbox 360 version...

Solarquest kicks the original Monopoly's ass. It's awesome that someone else has that game, you're the first person I know of outside my family who has even heard of it. I love making enough money to afford enough battles to roll double-sixes and take someone out permanently. Also, buying up every single moon around Jupiter or Saturn, and some poor guy doesn't have enough fuel to break orbit and I can price gouge them to death.

[EDIT]: I just realized that Mynt isn't naming another game, but making a Solarquest reference... I now know two outside my family who play this game. Sweet.

Risk, by far my favorite.
